Available in PDF, EPUB and Kindle. Book excerpt: Comprehensive overview of strategies and applications of cross-dehydrogenative coupling methods Cross-Dehydrogenative Coupling (CDC) represents a type of coupling reaction for the construction of a C–C bond or C–heteroatom (C–X) bond directly from C–H and X–H bonds present in the precursors. Since this genre of coupling reaction obviates the need for substrate prefunctionalization, it has an added advantage of high efficiency, atom economy, and environmental friendliness. CDC reactions are triggered by transition-metal catalysts or simply by an oxidants, or by either photocatalysis or electrocatalysis, leading to a hetero- or homo-coupled products with the removal of two hydrogens. Over the years, several CDC strategies have been developed that has made it possible to construct bonds between carbon-hydrogen (C–H) bonds of diverse hybridization. CDC has also streamlined the synthesis and functionalization of various nitrogen, oxygen, and sulfur-containing heterocycles. This volume features a series of chapters systematically covering methods and strategies in CDC, organized primarily on the type of bond being formed. In addition, particular aspects of CDC are highlighted in devoted chapters on topics such as mechanistic aspects, electrochemical and flow methods, transformations in water, natural product synthesis, and enantioselective protocols.

This book was released on 2020-05-22 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: The widespread use of organoboron compounds justifies the efforts devoted to their synthesis, as well as toward developing an understanding of their reactivity. The nature of the mono- or diboron species is of paramount importance in determining the reversible covalent binding properties of the boron atom with both nucleophiles and electrophiles. By wedding the rich chemical potential of organoboron compounds to the ubiquity of organic scaffolds, advanced borylation reactions have the potential to open unprecedented synthetic alternatives, and new knowledge in the field should encourage chemists to use organoboron compounds. In this volume, the main objective is to provide a collection of the most useful, practical, and reliable methods, reported mainly within the last decade, for boron activation and boron reactivity. The volume covers the main concepts of organoboron compounds and includes experimental procedures, enabling newcomers to the field the instant and reliable application of the new tools in synthesis. Rather than aiming for a comprehensive coverage, the most advanced solutions for challenging transformations are introduced. To this end, a team of pioneers and leaders in the field have been assembled who discuss both the practical and conceptual aspects of this rapidly growing field.

Available in PDF, EPUB and Kindle. Book excerpt: In this Special Issue, recent advances in cross-coupling reactions are presented in the form of original research articles, reviews, and short communications.

The original research articles present the synthesis of 2-alkynylpyrrols by inverse Sonogashira coupling and the synthesis of indoles under oxidative dearomative cross-dehydrogenative conditions. The efficient combination of iridium-catalyzed C–H borylation of aryl halides with the Sonogashira coupling and a sequential iridium-catalyzed borylation of NH-free pyrroles followed by a Suzuki–Miyaura reaction are included. The synthesis of aryl propionic acids, a common structural motif in medicinal chemistry, and the synthesis of new organic dyes are also covered.

Download or read book Mechanochemical Organic Synthesis written by Davor Margetic and published by Elsevier. This book was released on 2016-04-23 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mechanochemical Organic Synthesis is a comprehensive reference that not only synthesizes the current literature but also offers practical protocols that industrial and academic scientists can immediately put to use in their daily work. Increasing interest in green chemistry has led to the development of numerous environmentally-friendly methodologies for the synthesis of organic molecules of interest. Amongst the green methodologies drawing attention, mechanochemistry is emerging as a promising method to circumvent the use of toxic solvents and reagents as well as to increase energy efficiency. The development of synthetic strategies that require less, or the minimal, amount of energy to carry out a specific reaction with optimum productivity is of vital importance for large-scale industrial production. Experimental procedures at room temperature are the mildest reaction conditions (essentially required for many temperature-sensitive organic substrates as a key step in multi-step sequence reactions) and are the core of mechanochemical organic synthesis. This green synthetic method is now emerging in a very progressive manner and until now, there is no book that reviews the recent developments in this area. - Features cutting-edge research in the field of mechanochemical organic synthesis for more sustainable reactions - Integrates advances in green chemistry research into industrial applications and process development - Focuses on designing techniques in organic synthesis directed toward mild reaction conditions - Includes global coverage of mechanochemical synthetic protocols for the generation of organic compounds

Download or read book Cross Coupling Reactions written by Norio Miyaura and published by Springer. This book was released on 2003-07-01 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1972, a very powerful catalytic cycle for carbon-carbon bond formation was 2 first discovered by the coupling reaction of Grignard reagents at the sp -carbon. Over the past 30 years, the protocol has been substantially improved and expanded to other coupling reactions of Li,B,N,O,Al,Si,P,S,Cu,Mn,Zn,In,Sn, and Hg compounds. These reactions provided an indispensable and simple methodology for preparative organic chemists. Due to the simplicity and rel- bility in the carbon-carbon, carbon-heteroatom, and carbon-metalloid bo- formations,as well as high efficiency of the catalytic process,the reactions have been widely employed by organic chemists in various fields. Application of the protocol ranges from various syntheses of complex natural products to the preparation of biologically relevant molecules including drugs, and of sup- molecules, and to functional materials. The reactions on solid surfaces allow robot synthesis and combinatorial synthesis. Now, many organic chemists do not hesitate to use transition metal complexes for the transformation of org- ic molecules. Indeed, innumerable organic syntheses have been realized by the catalyzed reactions of transition metal complexes that are not achievable by t- ditional synthetic methods. Among these, the metal-catalyzed cross-coupling reactions have undoubtedly contributed greatly to the development of such a new area of “metal-catalyzed organic syntheses”. An excellent monograph for the cross-coupling reactions and other met- catalyzed C-C bond-forming reactions recently appeared in Metal-catalyzed Cross-coupling Reactions (Wiley-VCH,1998).
